SPECIFICATION forming Application filed August 18, 1881!.

(N0 model.) Patented in England January 23, lBTT, No, 289.

T0 aZZ whom it may concern:

Be it known that I, THADDEUS HYATT, of the city, county, and State of New York, have invented certain new and useful Improvements in Vault or Combination Daylight-Reflector Roofs and Roof-Pavements; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, making part of this specification.

The object of my improvements is to modify and control the shadow cast beneath them by daylight-reflectors, when placed underneath glass roofs and roof-pavements, to illuminate the far-off parts of the apartment, daylight reflectors, as usually made, being in the form of a large plate or surface, with no breaks or openings of any kind in it, to let a portion of the light from above pass through to the under side.

My invention consists in making the reflector to open and shut like a hot-air register, made of pivoted louvers hitched together, like Venetian blinds, or made of two flat slotted plates sliding one over the faceof the other, the Venetiarrblind plan being the one preferred.

The invention consists, furthermore, in hinging the register-reflector at top to swing, so as to be set at any desired angle, the compound movements produced by varying the angle of the slats in the frame, and varying the inclination or slope of the frame itself, enabling the occupant of the apartment to regulate the degree of light or shade at will.

Figure 1 represents a register-reflector roof over the rear extension of the principal story or ground-floor of a building.

Fig. 2 represents a register-reflector area roof or stoop in front of the building over the basement extension; A, illuminating arearoof or stoop; B, daylight register-reflector; O, basement-extension; D, extension of the principal story at the rear; to a, mirror or daylightreflector slats; I) b, frame carrying the slats; c c, wire'or rod connecting the slats d, lever-handle at which wireterminates; e, wall-pulley for cord of reflector to p ass over; f,hin ge ofrefleetor where fastened at top; 9, pulley-cord for raising and lowering reflector.

' Fig. 3 represents an enlarged view of one of the slats; E, the body of the slat, made of wood; h 71, mirror-face on one surface of 'the slat; h h, mirror-face on the reverse surface,

rays of light represented by broken lines.

The novel features of my invention are, first, the open-andshut or register character of the daylight-reflector; second, a daylight-reflector composed of a frame and pivoted reflectingslats with mirror-faces; third, pivoted reflect.

ing-slats made with mirror-backs; fourth, a daylight-reflector composed of a frame and pivoted reflecting-slats, in which the slats are arranged in the frame upon a planethe reverse of their own slope; but my invention is not limited to having all the above in combination. I employ the term daylight-reflector, in the ordinary sense in which it is used, to mean a highly-p olished metal or silvered glass surface.

My register-reflector, as illustrated by the drawings, is made of pivoted slats (1, arranged in a frame, I), the slats being hitched together by the wire or rod 0, which is fastened to the lever-handle d, by turning which the whole of them may be opened or closed simultaneously or set to any required angle necessary to give the best effect to the light,

To avoid setting the slats too far apart to get light through them into the apartment u11- derneath them, the backs of the slats are faced with the daylight-reflectin g material, the effect of which is illustrated in Fig. 1, where the light-rays i it, reflected from the backs of the slats, descend into the space immediatelybelow the reflector.

The arrangement of the slats in a plane the reverse of the face of the slats themselves, and the reverse, too, of the slope of daylight-re flectors made in the ordinary way, serves a useful purpose in basementextensions, where the ceilings are low, and gives a better finish and effect to the rear portion of the principal story of a building, when employed there in. combination with the skylight, as shown in the drawings.

WVhat I claim. as my invention, and desire to secure by Letters Patent, is-

1.
